To classify a tumor in digital mammogram images, I have tested several families of features like ho moments, harralik moments, co-occurrence matrix and walwet.
Nabiha, we tested several techniques as you said, Haralick, co-occurence Matrix, wavelet, Randm Forest, Zipf 'Law, Inverse Zipf' Law, combination of agents and automata cat this moment we got a very good results with the combination of Zipf and Zipf Law better. Let's see what others say??
